Answer:
A. Theme.
Step-by-step explanation:
The phrase displays the "theme" as it indicates the subject of talk or can act as a central idea of writing that displays the author's purpose. The phrase is not an excerpt and neither employs alliteration nor suggests a conclusion instead it seems to be the recurring conflict, so, the third and fourth are incorrect. It cannot be a logical fallacy it illustrates a "flaw in reasoning" or "illusions of thought" which is also not the case here. Thus, it best suggests the theme as it hints the major conflict that has the ability to drive a narrative by displaying the characters' split between their wants and need and finally, reaching to a concluding remark as a sign of resolution.
